Fraser Institute fires off a damp squib

3 Feb 2007 by group

New addition: Download an annotated pdf of the Fraser report. An interactive pdf file, to be read on the screen, is here, and a printable version is here. Suggestions for further commenting are welcome. Additions to the pdf have to be short, and tied to particular pieces of text or figures. And of course we will only incorporate comments that we deem to be scientifically sound and cogent.

*****************

While most of the world’s climate scientists were following the IPCC fest last week, a few contrarians left out in the cold were trying to to organize their own party.

An unofficial, “Independent Summary for Policymakers” (ISPM) of the IPCC Fourth Assessment report has been delivered by the Fraser Institute. It’s a long, imposing-looking document, resembling, come to think of it, the formatting of the real Summary for Policymakers (SPM) document that was released on Friday after final negotiations of the IPCC in Paris last week. The Fraser Institute has assembled an awesome team of 10 authors, including such RC favorites as tilter-against-windmills-and-hockey-sticks Ross McKitrick, and other luminaries such as William Kininmonth, MSc, M.Admin — whose most recent paper is “Don’t be Gored into Going Along” in the Oct-Nov issue of Power Engineer. To be fair, he did publish a paper on weather forecasting, back in 1973. According to the press release, the London kickoff event will be graced by the presence of “noted environmentalist” David Bellamy. It’s true he’s “noted,” but what he’s noted for is his blatant fabrication of numbers purporting to show that the world’s glaciers are advancing rather retreating, as reported here.

The IPCC Fourth Assessment SPM

2 Feb 2007 by group

Translations: (Français) (Português) (Türkçe) (Español)

We’ve had a policy of (mostly) not commenting on the various drafts, misquotes and mistaken readings of the Fourth Assessment report (“AR4” to those in the acronym loop) of the IPCC. Now that the summary for policy makers (or “SPM”) has actually been published though, we can discuss the substance of the report without having to worry that the details will change. This post will only be our first cut at talking about the whole report. We plan on going chapter by chapter, hopefully explaining the key issues and the remaining key uncertainties over the next few months. This report will be referenced repeatedly over the next few years, and so we can take the time to do a reasonable job explaining what’s in it and why.

Quick pre-SPM round-up

1 Feb 2007 by group

Tomorrow is the big day for all IPCC-watchers (and we’ll comment then) but in the meantime here are a few interesting tidbits floating around today.

First off, there are some curious patterns in the whitehouse.gov search engine. It turns out that it has been blocked from returning most results if the search phrase includes “global warming” – even if it’s from the President himself. For instance, searching for “issue of global” gives as top result the President’s Rose Garden speech in June 2001 on Global Climate Change, but searching for “issue of global warming” (which of course is the full phrase used) returns nothing. Hmmm…..

Secondly, Bill Nye (‘the underprepared science guy’) had a rather rough time of it up against Richard Lindzen on Larry King last night – an episode notable only for the regression back to the ‘false balance’ notion that most of the media has been moving away from (sigh…). However, tucked away at the end was a rather confused section, where it appears that Lindzen bet Nye that ice cores don’t have a resolution better than 2000 years. Now this is an odd claim, and an odder thing to bet on, since Greenland cores (GRIP, GISP2) and Antarctic cores (EPICA DML) have sub-annual resolution in many cases for the isotope (temperature) records, and at least decadal resolution (Law Dome, Siple Dome) for the greenhouse gases (CO2, CH4). It’s true that the very longest records (Vostok and Dome-C) have coarser resolution, but surely Lindzen doesn’t think they are the only ones that exist? So, to make up for Nye’s performance, he should at least get a quality bottle of scotch. Bill, let us know if Lindzen pays up!

Finally, there is an excellent article on the sausage making going on in Paris… more on that tomorrow.

House and Senate committee hearings

30 Jan 2007 by group

There are two hearings today from the new congress that are of relevance for RealClimate readers:

The House Oversight Committee is having hearings on the possible suppression of climate change science by the administration (streaming from here). Witnesses include Drew Shindell (NASA GISS), Roger Pielke Jr. and R. Piltz. Update: Full hearing video available at C-SPAN.

The Senate EPW Committee is having an open forum for senators to discuss climate change legislation (streaming from here).

Stern Science

28 Jan 2007 by group

Translations: (Français) (Português)

Halldór Björnsson, William Connolley and Gavin Schmidt

Late last year, the UK Treasury’s Stern Review of the Economics of Climate Change was released to rapturous reception from all sides of the UK political spectrum (i.e. left and right). Since then it has been subject to significant criticism and debate (for a good listing see Rabbett Run). Much of that discussion has revolved around the economic (and ethical) issues associated with ‘discounting’ (how you weight welfare in the future against welfare today) – particularly Nordhaus’s review. We are not qualified to address those issues, and so have not previously commented.

However, as exemplified by interviews on a recent Radio 4 program (including with our own William Connolley), some questions have involved the science that underlies the economics. We will try and address those.

When the mites go up…

22 Jan 2007 by group

Guest Commentary from Andy Baker, U. of Birmingham

It doesn’t seem obvious really. Going underground into caves, removing stalagmites and analysing their isotopic composition isn’t the first thing you would do to look for past climate information. But for nearly 40 years, there has been an active, and growing research community that investigates the climate records preserved in these archives. Stalagmites have recently received high profile use in climate reconstructions, for example records from China and Norway have featured in Moberg’s last millennium temperature reconstruction; in a northern hemisphere temperature reconstruction of the last 500 years and even been debated here on RealClimate. So it seems timely to review why on (or even under) earth should research go underground to look at surface climate.

Calling All Science Teachers

15 Jan 2007 by group

“An Inconvenient Truth,” the Davis Guggenheim documentary on global warming starring Al Gore’s presentation on the subject, provides an accurate, engaging, accessible, thought-provoking and (at times) even humorous introduction to one of the most important scientific issues of our time ( see our review of the movie). In some countries, viewing “An Inconvenient Truth” has actually become a required part of the science curriculum, and with good justification, we think. Given that the DVD is currently selling for $19.99 through Amazon.com, you’d think that the National Science Teachers’ Association ( NSTA) would jump at the chance to quickly get 50,000 free copies quickly into the hands of their members. Yet, when Laurie David, one of the producers of the film, made this offer to NSTA last November, it was summarily turned down on the grounds that the NSTA has a 2001 policy against “product endorsement” (as if Laurie David were trying to shop some new deodorant to high school science teachers). What in the world is going on here?

Before continuing with the history of NSTA’s bizarre decision, let us provide you with the most important information: Up to 50,000 US science teachers can receive a free copy of the DVD by filling out a simple request form here . The deadline for requesting your copy is January 18, so if you want a copy, take a few minutes to put in your request right away.

Arctic Sea Ice decline in the 21st Century

12 Jan 2007 by group

Translations: (Français)

Guest Commentary by Cecilia Bitz, University of Washington

Last month a paper I co-authored received considerable media attention. Headlines read “Experts warn North Pole will be ‘ice free’ by 2040”, “The Big Melt: Loss of Sea Ice Snowballs“, and “Arctic Clear for Summer Sailing by 2040: Models Predict Rapid Decline of Sea Ice”. The story also reached NPR, BBC, CBC, the Discovery channel, and Fox News, among others. Dr. Marika Holland, the first author of the paper, was inundated with media attention. About a dozen journalists contacted me too. I was impressed by the questions they posed — questions that probably reflect what the public most wants to know. However, after giving lengthy interviews, I would read the resulting article and see my explanations boiled down to a few lines. In this essay, I’d like to explain the science in the paper and give my answers to the most often asked questions.

Consensus as the New Heresy

3 Jan 2007 by group

Gavin Schmidt, Michael Mann, David Archer, Stefan Rahmstorf, William Connolley, and Raymond Bradley

Andy Revkin, who’s one of the best journalists on the climate beat, wrote a curious piece in the NY Times discussing the ‘middle stance’ of the climate debate. It’s nice to see news pieces on climate that aren’t breathless accounts of a new breakthough and that take the time to point out that the vast majority of relevant scientists take climate change extremely seriously. To that extent, the message of this piece was a welcome one. The curious part, however, was the thread running through the piece that this middle ground is only now emerging, and even curiouser, that this middle ground can be characterized as representing some sort of ‘heresy’.

Heresy, is commonly defined as ‘an opinion or doctrine at variance with the official or orthodox position’. So where does this idea come from, and why is it now ’emerging’?

2006 Year in review

27 Dec 2006 by group

Translations: (Français)

A lighthearted look at the climate science goings-on over the last year:

Best highlight of the gap between the ‘two cultures’:
Justice Scalia: ‘Troposphere, whatever. I told you before I’m not a scientist. That’s why I don’t want to have to deal with global warming’ .

Least effective muzzling of government climate scientist by a junior public affairs political appointee:
George Deutsch met his match in Jim Hansen.

Most puzzling finding that has yet to be replicated:
Methane from plants

Worst reported story and least effectual follow-up press release:
Methane from plants

Best (err… only) climate science documentary on public release:
An Inconvenient Truth.

Most worn out contrarian cliche:
Medieval English vineyards.

Previously prominent contrarian cliche curiously not being used any more:
“The satellites show cooling”

Most bizarre new contrarian claim:
“Global warming stopped in 1998”.
By the same logic, it also stopped in 1973, 1983, and 1990 (only it didn’t).

Most ironic complaint about ‘un-balanced’ climate coverage on CNN:
Pat Michaels (the most interviewed commentator by a factor of two) complaining that he doesn’t get enough exposure.

Most dizzying turn-around of a climate skeptic:
Fred Singer “global warming is not happening” (1998,2000, 2002, 2005) to global warming is “unstoppable” (2006)

Best popular book on the climate change:
Elizabeth Kolbert’s “Field Notes from a Catastrophe”

Least unexpected observations:
(Joint winners) 2006 near-record minima in Arctic sea ice extent, near-record maxima in Northern Hemisphere temperatures, resumed increase in ocean heat content, record increases in CO2 emissions

Best resource for future climate model analyses:
PCMDI database of IPCC AR4 simulations. The gift that will keep on giving.

Best actual good news:
Methane concentrations appear to have stabilised. Maybe they can even be coaxed downward….

Biggest increase in uncertainty as a function of more research:
Anything to do with aerosols.

Least apologetic excuse for getting a climate story wrong:
Newsweek explains its 1975 ‘The Cooling World’ story.

Most promising newcomer on the contrarian comedy circuit:
Viscount Monckton of Brenchley

Least accurate attempted insinuation about RealClimate by a congressional staffer:
‘There’s so much money’: Marc Morano (Senate EPW outgoing majority committee staff, 5:30 into the mp3 file)

Boldest impractical policy idea:
Geo-engineering

Boldest practical policy idea:
Creation of a National Climate Service, which could more effecitvely provide useful climate information to policymakers.

Most revealing insight into the disinformation industry (fiction):
Thank you for smoking

Most revealing insight into the disinformation industry (non-fiction) and year’s best self-parody:
‘CO2 is life’

Feel free to suggest your own categories and winners…
